The novel anthraquinone compounds of the invention are characterized by the presence therein of at least one triazolylthio group and conform to the formu las lA.'A- [RTSRH]n wherein A is an anthraquinone radical; R and R each is an organic radical; T is a triazolyl radical; m is or 1; andnis 1,2, 3 or4.

The compounds of the invention produce yellow to greenish-blue shades on hydrophobic textile materials such as cellulose acetate, polyamide and polyester fibers. The novel compounds, in general, exhibit improved fastness properties such as fastness to light and resistance to sublimation. Many of the novel compounds are unique in that they possess excellent sublimation fastness on polyester fibers and also produce heavy shades on cellulose acetate fibers. Many also show excellent wash fastness on cellulose acetate and polyamide textile materials. Certain of the anthraquinone compounds possess superior build-up on polyester materials when compared to other sublimation-resistant anthraquinone dyes. Another advantage of the novel anthraquinone compounds is the bifunctionality of the triazolyl radical which permits the linkage of two or more chromophoric anthraquinone groups in a single molecule. Thus, dye compounds having two or more chromophoric anthraquinone groups can be synthesized to give approximately the same hue and strength of dyeing as is produced by an equimolar mixture of dye compounds containing one of the anthraquinone groups. Such combinations of chromophoric groups in a single molecule result in a sublimation fast dye which also exhibits good affinity for and build-up on hydrophobic textile materials. The characterization of the novel anthraquinone compounds as water-insoluble means that the compounds are sparingly soluble in water, i.e. substantially water-insoluble, due to the absence of water solubilizing groups such as sulfo and salts thereof.

The compounds of the invention in which the mercaptotriazolyl group is attached directly to a nuclear carbon atom of the anthraquinone nucleus are represented by the formula II. A(ST),, wherein the sulfur atom of ST is attached to a ring carbon atom-of anthraquinone radical A and to a ring carbon atom of triazolyl radial T. The compounds of .formula (II) can be employed in the preparation compounds having the formula III. ASTR"-TSA wherein T is a triazoldiyl radical, e.g. a 1,3-triazoldiyl group, and R" is an alkylene group which is attached to the secondary nitrogen atom of each of the triazoldiyl groups. Compounds containing two anthraquinone nuclei joined by an organic group having one mercaptotriazoldiyl group are illustrated by the formula wherein R is defined above. The novel anthraquinone compounds can contain a plurality of mercaptotriazole groups joined by alkylene bridges alternatively attached to the secondary nitrogen atoms of two triazole groups and to the sulfur atoms of two triazolylthio groups. These compounds are illustrated by the form ula The compounds of the invention in which the mercaptotriazolyl group is not attached directly to a nuclear carbon atom of the anthraquinone nucleus have the formulas VIA.

For ex-' ample, the compound of Example 164 is 1,4-dihydroxy-5,8-di[2-( lH-l ,2,4-triazol-3-ylthio)ethylamino]- anthraquinone.

The novel anthraquinone compounds of the invention have been described in detail with particular reference to preferred embodiments thereof, but it will thereof can be effected within the spirit and scope of the invention.

The compounds of the invention can be used for dyeing hydrophobic textile materials in the manner described in U.S. Pat. Nos. 2,880,050; 2,757,064; 2,782,187; and 3,043,827. The compounds can be applied to such materials from aqueous dyebaths at temperatures of from about 80 to 100 C. at atmospheric or superatmospheric pressures. Various carriers, surfactants, and dispersing agents also can be present in the dyebath if desired. The dyeing techniques describedin U.S. Pat. No. 3,313,590 can be employed, using various solvents and carriers such as o-phenylphenol, biphenyl, butyl benzoate, methyl naphthalene, etc. The following examples illustrate procedures for applying the novel anthraquinone compounds to hydrophobic textile materials.

EXAMPLE 179 The triazolylthioanthraquinone compound of Example 4 (0.1 g.) is dissolved in 10 cc. of 2-methoxyethanol. A small amount (3-5 cc.) of a 3 percent sodium lignin sulfonate aqueous solution is added, with stir- 5 ring, and then the volume of the bath is brought to 300 cc. with water. 3 cc. of an anionic solvent carrier (Tanavol) is added to the bath and 10 grams of a textile fabric made of poly(ethylene terephthalate) fibers is placed in the bath and worked 10 minutes without heat. The dyeing is carried out at the boil for one hour. The dyed fabric is removed from the dyebath and scoured for 20 minutes at 80 C. in a solution containing 1 g./l. neutral soap and 1 g./l. sodium carbonate. The fabric is then rinsed, dried in an oven at'250 F. and heat set (for removal of residual carrier) for 5 minutes at 350 C.

EXAMPLE 180 0.1 g. of the anthraquinone product obtained in Example 7 is dissolved in 10 cc. of 2-methoxyethanol. A small amount (3-5 cc.) of a 3 percent sodium lignin sulfonate aqueous solution is added, with stirring, and then the volume of the bath is brought to 300 cc. with water. 10 g. of a textile fabric made of partially 5 hydrolyzed, cellulose acetate fibers (ESTRON fibers) is placed in the bath, worked for 10 minutes without heat, and then the bath is slowly brought to C. and the dyeing is continued for 1 hour. The dyed fabric is removed from the dyebath and scoured for 20 minutes I aat 80 C. in a solution containing 1 g./l. neutral soap The compounds of Table 11 wherein R represents;

and l g./l. sodium carbonate. The fabric is then rinsed and dried.

The dyeing procedure described in Example can be employed in the application of the novel anthraquinone compounds to polyamide textile materials except that the dyeing is carried out at the boil rather than at 80 C.

The compounds of the invention can also be applied to polyester textile materials by the heat fixation technique described in U.S. Pat. No. 2,663,6l2 and in EXAMPLE 181 A mixture of:

500 mg. of the compound of Example 34, 150 mg. of a sodium lignosulfonate dispersing agent (Marasperse N), 150 mg. of a partially desulfonated sodium lignosulfonate Marasperse CB), 0.5 ml. glycerin, and

1.0 ml. of water is ground in a microsize container (an accessory for a l-quart size Szegvari Attritor) for approximately 35 hours. Enough Aa-inch stainless steel balls are added to provide maximum grinding. When the grinding is complete, the entire contents are poured into a beaker and 100 ml. of water are used to washthe remaining dye paste from the micro-container. The'dye paste is then heated slowly to 65 C. with continuous stirring.

A thickener and-penetrating mixture is prepared by mixing 1 ml. of a complex diaryl sulfonate surfactant, (compound 8-5), 1

3 ml. of a 3 percent solution of a sodium N-methyl- N-oleoyltaurate (Igepon T-sl),

8 ml. of a 25 percent solution of natural gums Superclear 8ON), and sufficient water to bring the volume to 100 ml. The thickener and penetrating mixture is added to the dye paste, the volume is adjusted to 200ml. and the mixture is agitated for minutes. The dye mixtureis then filtered through folded cheesecloth to remove the stainless steel balls and it then is added to the reservoir of a Butterworth padder where it is heated to about 4560 C. 1

10 g. of a fabric of poly(ethylene terephthalate) fibers and 10 g. ofa fabric of 65/35 spun poly(ethylene terephthalate)/cotton fibers are sewn together, end-toend, and padded for 5 minutes of continuous cycling through the dye mixture and between three rubber squeeze rollers of the padder. Dye mixture pick-up is about 60 percent based on the weight of the fabrics.

The padded fabrics are then dried at 200 F. and then heat-fixed for 2 minutes at 415 F. in a forced air oven. The dyed fabrics are scoured for minutes at 65-70 C. in asolution containing 0.2 percent sodium hydrosulfite, 0.2 percent sodium carbonate and 1.7

percent of a 3 percent solution of sodium N-methyl-N- oleoyltaurate and then dried. The dyed fabrics possess excellent brightness and exhibit outstanding fastness to light and sublimation when tested according to the procedures described in the 1966 edition of the Technical Manual of the American Association of Textile Chemists and Colorists.

The heat fixation dyeing procedure described above can be varied by thesubstitution of other dispersing agents, surfactants, suspending agents, thickeners, etc. The temperature and time of the heat-fixation step can also be varied.

Polymeric linear polyester materials of the terephthalate sold under the trademarks Kodel," Dacron and Terylene are illustrative of the linear aromatic polyester textile materials that can be dyed with the compounds of our invention. Examples of linear polyester textile materials that can be dyed with the compounds of the invention are those prepared from ethylene glycol and dimethylterephthalate or from cyclohexanedimethanol and dimethylterephthalate. Polyesters prepared from cyclohexanedimenthanol and dimethylterephthalateare more particularly described in US. Pat. No. 2,901,446. Poly(ethylene terephthalate) polyester fibers are described, for example, in U.S. Pat. No. 2,465,319. The polymeric linear polyester materials disclosed in US. Pats. Nos. 2,945,010; 2,957,745; and 2,989,363, for

example, can be dyed. The linear aromatic polyester materials specifically named have a melting point of at least 200 C. The poly(ethylene terephthalate) fibers which are dyed with the compounds of the invention are manufactured from a melt of a polymer having an inherent viscosity of at least 0.35 and preferably, about 0.6. The inherent viscosity of the poly( l,4-cyclohexylenedimethylene terephthalate) polymer is also at least 0.35; These inherent viscosities are measured at 25 C. using 0.25 g. polymer per ml. of a solvent consisting of 60 percent phenol and 40 percent tetrachloroethane. The polyester fabrics, yarns, fibers and filaments that are dyed with the novel compounds can also contain minor amounts of other additives such as brighteners, pigments, delusterants, inhibitors, stabilizers, etc. I

Examples of the polyamide textile materials that can be dyed with the novel anthraquinone compounds are those consisting of nylon 66, made by the polymerization of adipic acid and hexamethylenediamine, nylon 6, prepared from epsilon-aminocaproic acid lactam, and nylon 8. Fibers, yarns and fabrics prepared from either unhydrolyzed or partially-hydrolyzed cellulose acetate can be dyed with the compounds of the invention.

The novel anthraquinone compounds can be converted to the corresponding cationic compounds by treating the novel com-pounds with an alkylating agent at elevated temperatures and/or pressure. The cationic compounds prepared from the compounds of the invention are useful as dyes for modacrylic, acrylic and acid-modified polyester textile materials. The following example illustrates the alkylation of the novel compounds to prepare the analogous cationic compounds.
